Abstract

A pepper grinder has a grinding assembly (2) including an inner grinding member (23) and an outer grinding member (22) turnable relative to each other to grind pepper in between. The outer grinding member (22) is secured in a lower housing member (1) by means of a lower securing ring (26) connected to the outer grinding member (22); the securing ring (26) has saw teeth (262) projecting from an upper edge, and is pressed into the lower housing (1) for the pointed ends of the saw teeth (262) to be inserted into the inner side of the lower housing (1) such that the outer grinding member (22) can't turn relative to the lower housing (1). The inner grinding member (23) is also secured to an upper housing (3) by a securing ring (25) of the kind. Thus, the inner grinding member (23) can turn relative to the outer one when the upper housing (3) is turned relative to the lower housing (1).

Description

PEPPER GRINDER BACKGROUND OF THE INVENTION Pepper is a main seasoning in dining. Peppercorns are the original form of pepper, and have to be crushed into small pieces before they are provided on the dining table.

Many kinds of pepper grinders have been devised to crush peppercorns into small pieces. Referring to Fig. 5, one of the conventional pepper grinders 4 has a grinding assembly 42 having an inner grinding part and an outer grinding part turnable relative to each other to grind pepper in between. The inner grinding part of the grinding assembly 42 is fixedly housed in an upper housing member 41, and the outer grinding part of the grinding assembly 42 is fixedly housed in a lower housing member 43 such that a user can turn the upper housing member 41 relative to the lower housing member 43 to grind pepper between the inner grinding part and the outer grinding part; the lower housing member 43 has a bottom opening 431 for small pieces of ground pepper to be dispensed therefrom.

Because the grinding parts of the grinding assembly 42 are attached to the housing members 41 and 43 by means of hot melt adhesive, the pepper grinder is found to have disadvantages as follows: I. When the hot melt adhesive is not applied to the joint between the grinding assembly and the housing members enough, the grinding assembly can't be secured to the housing members. When the hot

melt adhesive is applied to the joint too much, same will form hairy edge on the housing members, and consequently, the housing members can't turn relative to each other smoothly.

2. The grinding assembly is likely to loosen on the housing members after long time of use.

SUMMARY OF THE INVENTION Therefore, it is a main object of the present invention to provide a pepper grinder which has a grinding assembly capable of being easily and securely housed in the housing members.

The pepper grinder has a grinding assembly including an outer grinding member and an inner grinding member; the grinding members have opposing grinding teeth such that pepper can be ground in between when one turns relative to the other.

The outer grinding member is secured in a lower housing member by means of a lower securing ring; the lower securing ring has saw teeth projecting upwards, and the saw teeth are inserted into an inner side of the lower housing member from pointed ends. The lower securing ring is also connected to the outer grinding member such that the latter can't move relative to the lower housing member.

The inner grinding member is connected to a locating member, which is also secured to an upper housing member by means of a securing ring of the kind such that the grinding member can't turn relative to the upper housing member. Therefore, when the upper housing member is turned

relative to the lower housing member, the inner grinding member can turn relative to the outer grinding member to grind pepper in between.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to Fig. 1, a pepper grinder of the present invention has a lower housing member 1, a grinding assembly 2 and an upper housing member 3.

The lower housing member 1 has an annular locating protrusion I I on an inner side, and an opening 12 on a bottom. Both the lower and the

upper housing members 1 and 3 can be made of wood, plastic or metal.

The grinding assembly 2 has a locating member 21, an outer grinding member 22, an inner grinding member 23, an adjustment knob 24, an upper securing ring 25 and a lower securing ring 26.

The outer grinding member 22 is disposed in the lower housing member 1 with a bottom supported by the annular locating protrusion 11 of the lower housing member 1. The outer grinding member 22 has several connecting protrusions 223 on an outer side, and a toothed element 221 disposed therein; the toothed element 221 has grinding teeth 222 on an inner side.

The lower securing ring 26 has saw teeth 262 spaced apart, and at least slightly bent outwardly from an upper edge. The lower securing ring 26 further has several gaps 261 on an inner side. The lower securing ring 26 is pressed into the lower housing member 1 with the gaps 261 connecting the connecting protrusions 223 of the outer grinding member 22; the saw teeth 262 being inserted into the inner side of the lower housing member 1 from the pointed ends to present the lower securing ring 26 from moving relative to the lower housing member 1. Thus, the outer grinding member 22 is secured to the lower housing member 1.

The locating member 21 has several gaps 213 on an outer side, and a connecting rod 211 projecting from a center of the bottom. The locating member 21 is disposed in the upper housing member 3, and confined by an annular locating protrusion (not numbered) of the inner side of the upper housing member 3.

The upper securing ring 25 has saw teeth 252 spaced apart, and

slightly bent outwardly from a lower edge. The upper securing ring 25 further has connecting protrusions 251 on an inner side. The upper securing ring 25 is pressed into the upper housing member 3 with the connecting protrusions 251 fitted onto the gaps 213 of the locating member 21; the saw teeth 252 being inserted into the inner side of the upper housing member 3 from the pointed ends to prevent the upper securing ring 25 from moving relative to the upper housing member 3.

Thus, the locating member 21 is secured to the upper housing member 3.

The inner grinding member 23 has grinding teeth 231 on an outer side, and is connected to the connecting rod 211 of the locating member 21, an elastic member 212 biasing same downwards, and tumably received in the toothed element 221. The adjustment knob 24 is disposed on the bottom of the inner grinding member 23, and connected to a lower threaded end portion of the connecting rod 211 of the locating member 21 in order to secure the inner grinding member 23 to the locating member 21; the adjustment knob 24 can be turned to adjust a position of the inner grinding member 23 relative to the outer grinding member 22.

Thus, the inner grinding member 23 can turn relative to the outer grinding member 22 to grind pepper between the grinding teeth 222 and 231 into small pieces when the user turns the upper housing member 3 relative to the lower housing member 1. Ground pepper particulates are dispensed through the opening 12 of the lower housing member 1.

The upper housing member 3 has an annular locating protrusion 31 formed in a lower position of the upper housing member 3. The upper housing member 3 further has a cover 32 for an upper opening where

pepper is put into the pepper grinder. Referring to Fig. 2, the cover 32 has securing protrusions 321 opposing the inner side of the upper housing member 3 when same is coupled to the housing member 3; thus, the cover 32 can be coupled to the housing member 3 more firmly.

From the above description, the pepper grinder of the present invention can be known to have desirable features as follows: 1. The locating member 21 and the outer grinding member 22 can be securely and easily fixed to the housing member 3 and 1 respectively by means of the upper and lower securing rings 25 and 26.

2. The securing rings 25 and 26 are connected to the locating member 21 and the outer grinding member 22 by means of fitting the - connecting protrusions 251 and 223 onto the gaps 213 and 261 so the locating member 21 and the outer grinding member 22 can't loosen on the securing rings 25 and 26 even after long time of use.

3. The cover 32 can be relatively firmly coupled to the upper housing member 3 because of the securing protrusions 321, i. e. same is protected from accidentally falling off the pepper grinder.
