Arukh HaShulchan, Orach Chaim 314:20-26
Sugya Map
The halakhic matrix governing the dismantling of containers on Shabbat rests upon a foundational tension: the collision of Melakhot of construction—specifically Boneh (building), Soser (demolishing), and Makeh B'Patish (striking the final blow)—with the pragmatic necessity of accessing food.
- Primary Issue: Under what conditions does the physical opening or destruction of a sealed container (a vessel, or keli) to retrieve its contents constitute a forbidden act of building, demolishing, or completing a vessel on Shabbat?
- The Nafka Minas (Practical Ramifications):
- The Ontological Status of the Container: Is a completely sealed, single-use container classified as a keli prior to opening, or does its opening physically "create" the vessel?
- The Nature of the Breach: Does the structural destruction of a container constitute Soser in vessels (Soser b'Kelim), or is it classified as permitted destruction (kilkul)?
- Modern Packaging: The halakhic status of opening modern tin cans, plastic bottle caps with breakable rings, and cardboard milk cartons.
- Primary Sources: Shabbat 146a, Beitzah 33b, Mishneh Torah, Sabbath 23:2, and Shulchan Aruch, Orach Chaim 314:1.

שוברין חבית לאכול הימנה גרוגרות, ובלבד שלא יתכוין לעשות פתח.
— Shabbat 146a; cf. Shulchan Aruch, Orach Chaim 314:1
ודבר זה ברור דקופסאות ותיבות קטנות שלנו שמביאים בהם צוקר וכה"ג... ודאי מותר לשברן ולקלקלן לגמרי כדי ליטול מה שבתוכם, דאין זה סתירת כלי כלל... דאינם עשויים לקיום כלל, ומיד כשמתרוקנים משליכים אותם לחוץ...
— Arukh HaShulchan, Orach Chaim 314:26
Philological and Structural Nuances
In Shabbat 146a, the Gemara permits "breaking" (soverin) a barrel to access dried figs. The linguistic choice of soverin (shattering/breaking) rather than potchin (opening) is highly deliberate. It indicates a destructive, non-functional breach.
The Arukh HaShulchan in Arukh HaShulchan, Orach Chaim 314:26 seizes upon this distinction, employing the term kilkul gamur (total destruction). He contrasts this with the creation of a petach yafah (a beautiful/functional opening), which is the conceptual linchpin of the prohibition.
By analyzing the phrase einam asuyim l'kiyum klal ("they are not made for permanence"), the Arukh HaShulchan shifts the halakhic focus from the physical act of cutting or breaking to the teleological status of the vessel itself.
Readings
The halakhic landscape of Soser and Boneh in vessels is defined by four distinct conceptual systems, spanning from the Rishonim to the late Acharonim.

Permits breaking Restricts breaking
whole vessels. to flimsy vessels.
1. The Realist Structuralism of Rashi
Rashi, commenting on the sugya of soveret chavit in Shabbat 146a (s.v. "Mustaki"), adopts a highly restrictive view of the Talmudic allowance to break a barrel. He posits that the Gemara's permission is exclusively limited to a chavit shel mustaki—a vessel fashioned from broken clay shards that have been temporarily joined together with pitch.
Because the vessel’s structural integrity is already compromised and held together by a temporary adhesive, breaking it does not constitute genuine "demolishing" (Soser).
However, for a chavit sheleimah (a whole, structurally sound barrel), Rashi maintains that breaking it is strictly prohibited. For Rashi, the physical reality of a whole vessel is subject to the laws of Boneh and Soser. Assembling a solid vessel is akin to building, and dismantling it is akin to demolishing.
Thus, Rashi holds a realist view: physical stability and structural wholeness dictate the application of Soser b'Kelim.
2. The Functionalist Conceptualism of Tosafot
Tosafot (ad loc., s.v. "Soveret") vehemently reject Rashi’s limitation. They argue that the halakhic consensus follows the principle of ein binyan b'kelim v'ein stira b'kelim—there is no building or demolishing in vessels.
According to Tosafot, one may break even a completely whole and sturdy barrel (chavit sheleimah) to access food, provided one does not intend to fashion a functional opening (petach).
The conceptual innovation of Tosafot lies in their definition of Soser. They argue that stira is a category reserved exclusively for real estate (karka) or structures attached to the ground (ohel).
A detached vessel (keli), by its very nature, exists outside the metaphysical jurisdiction of Soser, unless the act of "destruction" is actually a highly constructive, professional-grade refinement (which would violate Makeh B'Patish).
If the act is purely destructive and aimed solely at extracting the contents, it is completely permitted l'chatchilah. The Rama in Shulchan Aruch, Orach Chaim 314:1 codifies this lenient view of Tosafot as the primary halakhic ruling.
3. The Teleological Functionalism of the Rambam
The Rambam in Mishneh Torah, Sabbath 23:2 presents a unique hybrid approach. He writes:
"We may break a barrel to eat from it... provided that one does not intend to make a hole that serves as an opening (petach)... and if one intends to make an opening, he is liable under the category of Makeh B'Patish, for there is no building or demolishing in vessels."
At first glance, the Rambam’s ruling seems self-contradictory. If "there is no building or demolishing in vessels," why is making an opening prohibited?
The Or Sameach (ad loc.) and the Maggid Mishneh explain that the Rambam distinguishes between structural building/demolishing and functional completion.
While you cannot violate the labor of Boneh by merely assembling a vessel, or Soser by dismantling it, you can violate Makeh B'Patish if your action imparts a new, functional utility to the object.
Creating a neat, reusable opening (petach) transforms a sealed, useless container into a functional dispenser. The prohibition is not based on the physical manipulation of the material, but on the teleological transition from non-vessel to vessel.
4. The Dynamic Pragmatism of the Arukh HaShulchan
Entering the late 19th century, Rabbi Yechiel Michel Epstein addresses the emergence of industrial packaging in Arukh HaShulchan, Orach Chaim 314:20-26. His analysis yields a revolutionary conceptual framework.
He focuses on the destination of the container. In paragraph 26, discussing boxes sealed with nails (teivot she'mesumrot), he argues that if a container is designed solely to transport goods and is destined for the garbage heap immediately upon opening (einam asuyim l'kiyum klal), it lacks the halakhic status of a keli (vessel) altogether.
Because it has no permanence, the act of ripping it open is not Soser (since there is no "vessel" to destroy) nor is it Makeh B'Patish (since no one intends to create a functional opening for future use).
The Arukh HaShulchan writes that even if one opens it carefully, it is permitted, because the subjective intent of the user and the objective lifespan of the object strip it of any shem keli (the formal status of a vessel).
5. The Formalist Objectivism of the Chazon Ish
To fully appreciate the Arukh HaShulchan's leniency, we must contrast it with the formalist approach of the Chazon Ish in Chazon Ish, Orach Chaim 51:11.
The Chazon Ish takes the diametrically opposed view regarding modern tin cans. He argues that a completely sealed tin can is not considered a vessel while sealed, because it is completely inaccessible and useless.
The moment one punctures and opens the can, however, one has transformed a useless piece of sealed metal into a functional receptacle capable of holding food.
Therefore, according to the Chazon Ish, the act of opening a tin can does not destroy a vessel (Soser); rather, it creates a vessel (Boneh or Makeh B'Patish).
The Chazon Ish focuses entirely on the objective, physical transformation of the object at the moment of the act:
- Before: Closed cylinder (useless).
- After: Open container (receptacle).
- Result: A violation of Boneh.
The Arukh HaShulchan, by contrast, focuses on the socio-economic reality of the object: it is trash in transition, and thus exempt from the laws of Shabbat construction.
| Authority | Core Principle | Status of Whole Vessel | Status of Disposable Can |
|---|---|---|---|
| Rashi | Realist Structuralism | Forbidden to break | Forbidden (structural integrity) |
| Tosafot | Ontological Exemption | Permitted to break | Permitted (no Soser in vessels) |
| Rambam | Teleological Functionalism | Permitted, but petach is Makeh B'Patish | Forbidden if it creates a usable container |
| Arukh HaShulchan | Dynamic Pragmatism | Permitted to break | Permitted (lacks shem keli due to impermanence) |
| Chazon Ish | Formalist Objectivism | Permitted to break | Forbidden (Boneh via creating a receptacle) |
Friction
The Ultimate Kushya: The Paradox of "Soveret Chavit" vs. "Nekeb Chadash"
The central friction in this sugya lies in the stark contradiction between two primary talmudic passages:
- In Shabbat 146a, the Gemara explicitly permits breaking a barrel to eat dried figs (soverin chavit).
- In Mishnah Shabbat 22:3, the Mishnah explicitly rules: "אין נוקבין נקב חדש בחבית" (We may not pierce a new hole in a barrel).
If there is indeed ein binyan v'stira b'kelim (no building or demolishing in vessels), as Tosafot and the Rama claim, why is piercing a new hole (nekeb chadash) prohibited? Conversely, if piercing a hole is prohibited because it constitutes building/completing a vessel, why is shattering the barrel permitted?

[How to Reconcile?]
Terutz A: The Taz/Magen Avraham Axis (Destruction vs. Refinement)
The Taz in Taz on Shulchan Aruch, Orach Chaim 314:1 and the Magen Avraham in Magen Avraham 314:3 resolve this contradiction by introducing a fundamental distinction between kilkul (destruction) and tikkun (improvement/refinement).
When one shatters a barrel (sovera), the act is entirely destructive. The barrel is ruined and can no longer function as a storage vessel. Because Soser in vessels is only rabbinically forbidden when done destructively (or entirely permitted according to Tosafot), and because it is done for the sake of accessing food (Ochel Nefesh), the Sages permitted it.
However, when one pierces a neat, small hole (nekeb) in a barrel to allow liquid to drain out, the act is highly constructive. One is not destroying the barrel; rather, one is upgrading it by adding a functional tap or spout.
This act of refinement does not destroy the vessel, but rather completes its utility, thereby violating Makeh B'Patish (or Rabbinic Boneh).
The distinction hinges not on the amount of physical force used, but on the functional outcome of the act: $$\text{Shattering} \rightarrow \text{Kilkul (Destruction)} \rightarrow \text{Permitted}$$ $$\text{Piercing a Hole} \rightarrow \text{Tikkun (Refinement)} \rightarrow \text{Forbidden}$$
Terutz B: The Ramban’s Ontological Definition of "Petach"
The Ramban in his Chidushei HaRamban on Shabbat 146a offers a deeper, more ontological resolution. He asks: what legally distinguishes a "breach" from an "opening" (petach)?
The Ramban posits that a petach (opening) is defined by its dual functionality: it is designed both for entry and exit, or for filling and emptying.
When one pierces a new hole (nekeb) in a wine barrel to slowly draw wine over a long period, that hole is intended to be used repeatedly. It is designed to let wine out, and potentially to be plugged and unplugged.
Because it is meant for ongoing, repeated use, it is halakhically classified as a petach, and creating it violates Makeh B'Patish.
On the other hand, when one shatters the top of a barrel of dried figs, one is making a wide, crude breach solely to extract the figs immediately. No one intends to use this jagged, broken top as a functional "doorway" to refill the barrel.
It is a one-way, terminal exit. Because it lacks the capacity for repeated, functional use (filling and emptying), it does not carry the halakhic status of a petach.
The Arukh HaShulchan in Arukh HaShulchan, Orach Chaim 314:22 adopts this Ramban as the foundation for his lenient rulings on modern packaging:
"And the difference is simple... for a hole made to empty and then close, and empty again, this is a real opening (petach gamur)... but to break it to take out the food, where one does not care about the opening at all, this is permitted."
Intertext
To understand the boundaries of Soser b'Kelim and the status of broken vessels, we must look at parallel halakhic systems where the lifecycle of a keli is defined: Hilkhot Yom Tov and Hilkhot Kelim (ritual purity).
1. The Yom Tov Parallel: "M'tza'atza'at" in Beitzah 33b
In the laws of Yom Tov, where certain forms of labor are permitted for the sake of food preparation (Ochel Nefesh), we find a parallel discussion regarding the manipulation of vessels.
The Mishnah in Mishnah Beitzah 4:4 states: "אין שוברין את החרס... לעשותו כלי" (We do not break a clay shard on Yom Tov... to make it a vessel, such as a support for a pot).
The Gemara in Beitzah 33b explains that although Ochel Nefesh is permitted, the Sages strictly forbade any act of Tikkun Keli (fashioning or repairing a vessel) on Yom Tov.
This provides a powerful cross-reference to our sugya: even when the Torah permits creative labor for the sake of eating, the creation of a functional tool or vessel (Makeh B'Patish) remains an absolute boundary.
This supports the Rambam's view that even if Soser and Boneh do not formally apply to vessels, Makeh B'Patish is a universal prohibition that cannot be overridden by the need to access food.
2. The Purity Parallel: "Shviri Kelim" in Mishnah Kelim 17:1
In the laws of ritual purity (Tumat Kelim), a vessel only contracts impurity if it is a functional receptacle. The moment a vessel is broken, it loses its status as a keli and becomes pure (tahor).
The Mishnah in Mishnah Kelim 17:1 establishes the metric for when a punctured or broken vessel ceases to be classified as a keli:
"All vessels of the householders... their measure of puncture is like pomegranates (k'rimonim)."
If a domestic barrel develops a hole large enough for a pomegranate to fall through, it is legally "destroyed" (shvurim) and can no longer contract impurity.
The Contrast between Shabbat and Tumah
This creates a fascinating conceptual contrast with our Shabbat sugya:
[Halakhic Definition of "Destruction"]
|
+---> Hilkhot Tumah: OBJECTIVE & MATERIAL (Physical capacity of the vessel)
|
+---> Hilkhot Shabbat: SUBJECTIVE & TELEOLOGICAL (Human intent / Melechet Machashevet)
In Hilkhot Tumah, the status of a vessel is purely objective and material. If it can physically hold pomegranates, it is a keli; if not, it is trash.
On Shabbat, however, the status is subjective and teleological, governed by the laws of melechet machashevet (thoughtful, purposeful labor).
Even if a tin can is physically intact and capable of holding liquid, if the user’s intent is to throw it away immediately after extracting the food, it loses its halakhic status of keli regarding the prohibitions of Soser and Boneh.
Conversely, even a tiny puncture (nekeb) that would not nullify impurity in Hilkhot Kelim is strictly forbidden on Shabbat if it is created with the intent to serve as a functional spout, because Shabbat law focuses on the creative intent of the human actor.
Psak/Practice
The modern application of these principles is one of the most vibrant areas of contemporary halakhic debate, with the Arukh HaShulchan serving as a primary lenient authority.

[The Strict View] [The Lenient View]
(Chazon Ish) (Arukh HaShulchan)
| |
- Sealed can = non-vessel. - Can/box = transient shell.
- Opening creates a receptacle. - Ripping it open is purely destructive.
- Forbidden as BONEH. - Permitted (lacks SHEM KELI).
1. Opening Tin Cans
The Strict View (Chazon Ish): As noted, the Chazon Ish Chazon Ish, Orach Chaim 51:11 forbids opening tin cans with a can opener on Shabbat, as the act of opening transforms a sealed cylinder into a functional cup/receptacle, violating Boneh.
The Lenient View (Arukh HaShulchan / Rav Shlomo Zalman Auerbach): Rav Shlomo Zalman Auerbach (Minchat Shlomo I:91) rules in accordance with the conceptual framework of the Arukh HaShulchan Arukh HaShulchan, Orach Chaim 314:26. Because the can is opened solely to access the food and is thrown into the trash immediately after use, it is never classified as a keli in the hands of the consumer.
The act of opening is merely the dismantling of a protective wrapper, not the creation of a vessel. Therefore, it is entirely permitted.
To satisfy all opinions, many contemporary authorities recommend puncturing the bottom of the can before opening it, or opening it in a destructive manner that renders it incapable of holding liquids, thereby avoiding the Chazon Ish’s concern of creating a usable vessel.
2. Plastic Bottle Caps (Tearing the Ring)
The Debate: Modern plastic soda and water bottles feature caps secured by a plastic ring that tears away upon first opening.
The Stringent View: Rav Yosef Shalom Elyashiv rules that unscrewing the cap for the first time completes the physical manufacture of the cap. Prior to opening, the cap and ring are fused as one unit; by unscrewing it and tearing the perforated plastic, one "creates" a functional, independent screw-cap. This is forbidden under Makeh B'Patish.
The Lenient View: Rav Shlomo Zalman Auerbach and the Shemirat Shabbat Kehilchatah (Ch. 9) permit opening these bottles. They argue that the cap was already fully manufactured and functional in the factory; the tearing of the ring is merely the removal of a seal, which does not constitute Makeh B'Patish.
This aligns perfectly with the Arukh HaShulchan’s principle that the removal of protective seals and bindings (hoteir u'mekatekh) is entirely permitted to access food on Shabbat.
Takeaway
The prohibition of building and demolishing on Shabbat does not apply to the destructive opening of transient, disposable food packaging, as their immediate destination for the trash bin strips them of the halakhic status of a "vessel."
